I am selling my 2 weeks old M2 Performance Exhaust. This exhaust sounds great, loud, perfect fitment and low drone. I personally compared with vanguard and the sounds like similar. I can say they are almost same. And also I have compared with Remus racing muffler. M2 exhaust was louder Remus. Because it was too loud. My girlfriend freaking hate to sit with my car. This is why I am selling it. This exhaust still on my car and I am planning to take it off tomorrow or coming Monday. $250 cash are firmed and local pickup only. Please feel free to contact me if you have any questions. Fit E90/E92 335i. Not sure will it fit XI model. Video are coming soon. Thank You!
